E-SI/A: The E-SI/A model gratings are designed to be installed in false floors with a reticular structure. The measurements of the E-SI/A model gratings are external, to replace a plate, half a plate or a lower portion. When ordering, it is necessary to know the thickness of the plate, to ensure that the plates and gratings are at the same level during assembly. The normal thickness of a plate is 32 mm (other measurements are possible).

In false floors without structure, the grating must be supported by a metal frame the size of a full plate, rigid enough to withstand the overload of the false floor.

Maximum weight supported according to APPLUS test 10/31700015:

- For L=599 x H=599.
- 625 kg (2500 kg m2) with uniform load.
- 325 kg in the case of a point load.

E-SI/AR. Linear air flow grille with horizontal fixed fins at 0º, made from non-anodised aluminium profiles and with flow regulation. When the grille has flow regulation, due to the space occupied by the four steel or aluminium supports where the reticular structure is attached, the length of the regulation will cover the length of the lower opening of the grille, but not its height, which will be 450 mm, leaving an opening on both sides of the grille without regulation.

Attachment: Supported on the structure of the technical floor. In false floors without structure, the grille must be supported on a metal frame the size of a whole plate, rigid enough to withstand the overload.

Finish: Non-anodised aluminium
